Comment (by vbraun):
The whole `ToricDivisor(X, int)` construction is a bit wonky. Thinking
about it, the fact that `ToricDivisor(X,0)` is not the trivial element in
this Abelian group is just confusing. I'd prefer to get rid of integer
arguments in it altogether, there are already enough ways to construct a
toric divisor. And you can always replace it with
`ToricDivisorGroup(X).gen(int)`, so its not like its a big loss. I'd like
to keep the convenience method `X.divisor(i)`, mind you. What do you
think?
